Shock machines for testing Arctic robotics

Abstract

All industrial products including robots used for various works in arctic zone, can be exposed to various shock loads. In arctic conditions, such loads are: tectonical impacts, impacts from snow mass and other phenomena. To confirm the durability of products exposed to shock loads during exploitation, the impact tests ma products should be preliminary carried out. Such tests are performed in special equipment - shock machines. Shock machines are complex highly automated equipment. The development and production of machines of this type require advanced high technology and serious financial investments. Therefore, a deep understanding of operation principles of shock-testing machines, their design and methods of adjusting is very important. In the current paper the structures and designs of several types of developed shock machines are analyzed in details: single-shock machine, multiple-shock machine, machine with a pneumatic accelerator. Data on the development of a positional multi-motor pneumatic drive by the High School of Automatics and Robotics of Peter the Great St. Petersburg Polytechnic University are presented. The interface of the operation panel of the multiple shock machine is described according to operating modes, recording and processing the results of measuring the parameters of the shock pulse. Directions of research in the field of synthesis of shock machines for testing Arctic robotics are defined.
